Managing Number Ranges
Some countries impose sequencing requirements related to tax filings or statutory reporting. In many countries, companies are legally required to prevent gaps in the numbering of official documents.
Additionally, certain business practices require different business units within the same corporation to maintain separate sequencing for similar documents such as purchase orders, sales orders, and supplier invoices.
Example: In Italy, the number of an official document is strictly related to the date the document was printed, and it is a common practice to have multiple number ranges for shipment and invoice documents. In Brazil, the number of an official document is related to a specific physical site, requiring multiple number ranges with a prefix identifying a site code.
Number range management (NRM) supports varied sequencing requirements on a global scale. Features include gap control and multiple number ranges for the same document type.
